Scada programs are being extensively used for controlling complex equipments and whole plants. From SCADA, we mean Supervisory Control and Data Acquisition. It is in use for various complex systems and uses highly advanced man machine interfaces.
These are managed via a central computer that can guide various devices connected to it. Many methods are used for communication between the master and the other devices. The most commonly used ones are Ethernet, radio links and modems. The data about various devices is gathered with the help of sensors.
Various communication interfaces are used due to which the data is transmitted in various forms. Thus converters have to be used for conversion of data. All the information reaches the central unit where it is processed and analyzed regularly.
All the information is stored in the central database. It is where all parameters of various equipments are continuously tracked and controlled. These can be modified if a read / write permission is provided to them. All the equipments located near or far, will have them monitored this way.
There are two types of parameters used. These are analogue or digital. The SCADA software fetches them continuously and stores them. The program can then makes its calculations based on all those stored parameters.
The calculations made by SACA program can then help in supervisory control and data acquisition. Modern Scada software shows you a graphical representation of various objects on the computer screen.
Various details are fetched from equipments used all over the industrial unit. Some important parameters are pressure, liquid level, temperature, etc. These details can be seen on the computer screen graphically too.
Advanced SCADA software also allows administrators to set up some functionality to alert them when any parameter reaches a certain value. Automatic SMS or email alerts can be set up. Thus a plant is controlled from a central location using SCADA systems. - 30201
